AIA A201 General Conditions: Responsibilities, Payments, and Claims

The AIA A201 General Conditions is the standard rulebook that gets folded into an AIA owner-contractor agreement and governs how a design-bid-build project actually runs: who is responsible for what, how payments move, how scope changes are documented, how delays and defects are handled, and how disputes get resolved.¹ It is the most widely used general conditions document in private commercial construction in the United States, and its 2017 edition is the current version.

How the A201 Attaches to Your Contract

The A201 does not stand alone. It is incorporated by reference into the primary owner-contractor agreement, such as the AIA A101 (stipulated sum) or A102 (cost-plus with a guaranteed maximum price).² Every provision of the A201 becomes legally binding through that reference, even if the parties never physically attach it to the signed agreement.

The full Contract Documents include the agreement, the general conditions, any supplementary conditions, the drawings, specifications, and any addenda issued before signing. They are read as a single unified obligation. If a requirement appears in the specifications but not on the drawings, the contractor is still responsible for performing that work. Bidding materials are not part of the Contract Documents unless the parties specifically list them.

No order of precedence exists by default. If two documents conflict, the parties and architect must resolve the inconsistency; no document automatically overrides another. Many project teams address this in the supplementary conditions before disputes arise.

Who Is Responsible for What

The Owner

The owner’s core duty is to pay for the work. The A201 adds a less obvious requirement: before construction begins, and at any point afterward if the contractor requests it, the owner must provide reasonable evidence that funding is in place to meet the contract obligations.³ The contractor has no obligation to start work until that evidence is provided.

If the contractor defaults or fails to correct deficient work, the owner has a self-help remedy. After seven days’ written notice, the owner can step in, correct the problem, and deduct the reasonable cost from payments owed. The architect must approve both the action and the amount. If the deductions exceed what the owner owes, the contractor pays the difference.

The Contractor

The contractor controls how the building gets built and has sole responsibility for construction methods, techniques, sequences, scheduling, and coordination of every trade and supplier. That control comes with matching liability: a method choice that causes a delay or defect is the contractor’s problem.

The contractor warrants that all materials and equipment will be new and of good quality and that the finished work will conform to the contract documents and be free from defects.⁴ The warranty does not cover damage from the owner’s abuse, unauthorized alterations, poor maintenance, or normal wear and tear.

Section 3.18 requires the contractor to indemnify the owner against claims for bodily injury, death, or damage to property other than the work itself, to the extent those claims result from the contractor’s negligence or the negligence of subcontractors and their employees.⁴ The indemnity does not extend to liability arising from the architect’s or owner’s own errors in design, specifications, or instructions. This is one of the most commonly modified provisions in supplementary conditions, so check whether your project expands or narrows the standard language.

The Architect

The architect serves as the owner’s representative and the initial administrator of the contract. They visit the site at intervals to observe progress and verify that the work aligns with design intent. The architect does not supervise the contractor’s employees or subcontractors and does not control construction means and methods. They interpret the contract documents, review payment applications, and act as the first decision-maker when disputes arise.

Subcontractors and Flow-Down

After the contract is awarded, the contractor must promptly notify the owner and architect of the subcontractors proposed for each major portion of the work. The architect has 14 days to object. Silence within that window counts as approval.⁵ If a rejected subcontractor was capable of performing the work, the contractor is entitled to a change order for any resulting cost or schedule difference.

Each subcontract must flow down the obligations of the A201, so subcontractors assume the same responsibilities toward the contractor that the contractor assumes toward the owner, including safety and warranty commitments.⁵ The flow-down preserves the owner’s and architect’s rights so a subcontractor cannot undermine the project’s legal framework through a side deal.

Payments, Retainage, and Pay-Through

The contractor begins by submitting a schedule of values that breaks the contract sum into allocated amounts for each portion of the work. Each month the contractor submits an Application for Payment reflecting work completed and materials stored. The architect reviews it, certifies the amount due, and the owner pays.

The owner withholds retainage from each payment, typically between five and ten percent of the amount earned. Upon Substantial Completion, the owner releases retainage adjusted for any incomplete or noncompliant work identified in the certificate.⁵ This is the single largest payment event at the end of most projects, and disputes over what qualifies as incomplete work often delay it.

Once the contractor receives payment from the owner, it must pay each subcontractor within seven days, reflecting the same retention percentages.⁵ When the contractor does not furnish a payment bond for the full contract sum, any payments received for subcontractor work must be held in trust for those subcontractors. Contractors must also provide lien waivers with each payment application to confirm that subcontractors and suppliers have been paid and the property remains free of encumbrances.

Changing the Scope

The A201 provides three mechanisms for changing the original scope. Which one applies depends on whether the parties agree and how large the change is.³

A Change Order is a written agreement signed by the owner, contractor, and architect that states the change in work, the adjustment to the contract sum, and the adjustment to the contract time. All three parties must agree before it takes effect.
A Construction Change Directive is used when the parties cannot agree on price or time. The owner and architect sign it, the contractor must proceed with the changed work immediately, and the final cost is negotiated afterward, typically based on actual costs plus an agreed markup. Ignoring a valid directive is a contract breach.
A Minor Change in the Work is a small adjustment ordered by the architect in writing that does not affect the contract sum or time. These typically address aesthetic or technical details.

Every modification must be documented in writing to be enforceable. Verbal agreements to change scope are a recurring source of disputes, and the A201 provides no mechanism to enforce them.

Contract Time, Delays, and Concealed Conditions

Contract Time runs from the commencement date until Substantial Completion, which the A201 defines as the stage when the work is sufficiently complete for the owner to occupy or use the building for its intended purpose. The architect issues a Certificate of Substantial Completion that assigns remaining responsibilities between the owner and contractor for punch-list items.

Adverse weather and other causes beyond the contractor’s control may justify a time extension under Article 8, but the contractor must assert the claim and the architect must approve it. Nothing happens automatically. Missing the claim window means absorbing the delay cost even when the cause was genuinely outside your control.

Concealed or unknown site conditions carry a similar deadline. If the contractor encounters subsurface conditions that differ materially from what the contract documents indicated, it must notify the owner and architect before disturbing the conditions and no later than 14 days after first observing them.⁴ Late notice can destroy an otherwise valid claim for additional money or time.

Defective Work and the Correction Period

When the architect or owner suspects work does not conform to the contract documents, they can require the contractor to uncover it for inspection. If the work was covered despite a specific request to leave it exposed, the contractor pays for uncovering and replacing it, with no time extension. If no such request was made, the owner can still order uncovering, but the contractor gets a change order for cost and delay if the work turns out to be compliant.³

After Substantial Completion, the contractor has a one-year correction period to fix any nonconforming work promptly after receiving notice from the owner.⁴ The period extends for any portions of work first performed after Substantial Completion. Corrective work done during this window does not restart the one-year clock. If the contractor fails to make corrections within a reasonable time, the owner can do the work itself and charge the contractor. If the owner fails to notify the contractor during this period, the owner waives the right to demand correction.

The owner also has the option to accept nonconforming work rather than requiring removal, in which case the contract sum is reduced by an appropriate amount. That reduction applies even after final payment.⁵

Safety and Hazardous Materials

The contractor bears full responsibility for job-site safety, including initiating and supervising all safety programs, complying with OSHA requirements, and protecting workers, the public, adjacent property, and stored materials.³ Any citations, fines, or penalties from regulatory agencies fall on the contractor, and the owner can terminate the contract for cause if the contractor fails to follow the safety procedures set forth in the contract documents.

Hazardous materials have their own rules. If the contractor encounters a suspected hazardous substance not addressed in the contract documents, it must stop work when the risk of bodily injury or death cannot be controlled with reasonable precautions, then notify the owner immediately.⁴ The contractor can engage a licensed lab to test the material, and the owner reimburses testing costs if the material is confirmed hazardous. Removal or disturbance of hazardous materials requires a negotiated change order. Liability tracks who brought the material to the site: the owner is responsible for pre-existing contamination, and the contractor is responsible for any hazardous materials it introduces and handles negligently.

Insurance, Bonds, and Waiver of Subrogation

The A201 requires both owner and contractor to carry insurance but deliberately leaves the specific types, coverage limits, and endorsements to be defined in the agreement or supplementary conditions.⁵ In practice, most projects require the contractor to maintain commercial general liability, automobile liability, workers’ compensation, and umbrella coverage. The owner may separately purchase builder’s risk and loss-of-use insurance.

The contractor must furnish surety bonds when the contract documents require them, purchased from a company authorized to issue bonds in the project’s jurisdiction.⁵ A performance bond guarantees the contractor will complete the work; a payment bond guarantees subcontractors and suppliers will be paid.

The A201 also includes a waiver of subrogation, which prevents one party’s insurer from suing another party to the contract to recover losses it paid on a covered claim. The practical effect is that a covered loss such as fire damage gets handled through insurance rather than through litigation between owner and contractor.

Termination

By the Owner for Cause

The owner can terminate the contractor for cause on four grounds: repeatedly failing to provide enough skilled workers or proper materials, failing to pay subcontractors or suppliers, repeatedly violating applicable laws and codes, or committing a substantial breach of the contract documents.⁵ For the first and third grounds, “repeatedly” is the operative word: a single violation is not enough. The owner must first obtain the architect’s certification that cause exists, then give the contractor seven days’ written notice. After termination, the owner may take possession of the site and use the contractor’s materials and equipment to finish the project.

By the Owner for Convenience

The owner can also terminate without any default by the contractor. The contractor is then entitled to payment for work properly completed plus reasonable costs incurred because of the termination, including costs of terminating subcontracts. The A201 explicitly excludes lost profits from this payment.⁴ If the owner pulls the plug halfway through, the contractor cannot recover profit on the unfinished half.

By the Contractor

The contractor’s thresholds are higher. If the work is stopped for 30 consecutive days through no fault of the contractor due to a court order, a government action, the architect’s failure to issue a payment certificate, the owner’s failure to pay, or the owner’s failure to provide evidence of financing, the contractor may terminate after giving seven days’ additional written notice.⁵ A separate provision allows termination if cumulative owner-caused delays exceed 100 percent of the total scheduled days or 120 days in any 365-day period, whichever is less. If the owner repeatedly fails to meet contract obligations and work stops for 60 consecutive days, the contractor can terminate on the same seven-day notice. Unlike an owner’s convenience termination, a contractor who terminates under these provisions can recover overhead and profit on work not yet performed.

Claims and Dispute Resolution

Article 15 establishes a structured, multi-step process, and the deadlines are unforgiving. A party seeking an adjustment to the contract sum or time must submit a written Notice of Claim within 21 days of the event giving rise to the claim. Missing that deadline often forfeits the right to any recovery, no matter how valid the underlying claim.

The claim first goes to the Initial Decision Maker, which is the architect unless the agreement designates someone else. The IDM reviews the claim and may approve it, reject it, or propose a compromise. If either party is dissatisfied, the dispute must go to mediation before any binding resolution can occur. Skipping mediation means an arbitrator or court can refuse to hear the case.

If mediation fails, the final resolution method is whichever the parties selected in their agreement, either arbitration or litigation. When arbitration is chosen, either party may consolidate the proceeding with related arbitrations involving common questions of fact or law and may join additional parties whose participation is necessary for complete relief, provided those parties consent in writing.⁴ Construction disputes frequently involve the owner, general contractor, subcontractors, and design professionals at once, so consolidation and joinder matter for avoiding inconsistent results in separate proceedings.

Supplementary Conditions Can Change Everything

The A201 is designed as a baseline, not a finished product. Nearly every project modifies it through supplementary conditions tailored to the specific deal. The most commonly modified provisions include the indemnification clause, insurance requirements, dispute resolution method, and the waiver of consequential damages. Some owners expand the indemnification to cover a broader range of claims; others add attorney’s-fee provisions for the prevailing party in litigation.

Read the supplementary conditions before assuming the standard A201 language applies. A provision that sounds protective in the general conditions may have been narrowed, broadened, or deleted entirely in the supplementary conditions. That is where the real negotiation happens, and overlooking it is one of the most common and expensive mistakes parties make on construction projects.
